The ISL58303 is a high-speed triple output laser diode driver designed to support color field sequential laser light source Pico projection modules. Outputs can be ganged together to achieve peak total current greater than 3.6A. Output channels are designed with independent programmable bias and threshold adjustment to support a wide range of laser diode manufacturers. The ISL58303 offers exceptional power efficiency and a high degree of system integration allowing a compact and cost effective system design.
To assist with reduction of laser speckle, this laser diode driver has a high frequency modulation input to modulate laser pulses. This can be used to achieve outputs pulses of less than 1ns.
Interface to the system is accomplished via a high-speed serial bus that is made up of SEN, SCLK and SDIO. Initialization of internal registers after power-on reset, operational setup and laser intensity data for each output channel are communicated through this bus.
For laser operational safety, a hardware enable signal (CE) is ANDed with an internal register bit. Both have to be asserted to enable the device. This prevents an accidental fault causing an unwanted laser output.
